Wow doesn't require an overly powerfull graphics card to play on basic/low settings. I leveled 2 toons to 80 playing on an Acer Extensa with ATI mobility graphics (which is a mere step above integrated I guess). Unless your video card is outright defective in some way I doubt it's to blame. I enjoy playing Wow so much that I upgraded to an Asus G72 with a 1GB GeForce 260M graphics card so I could play on ultra. I do notice a huge difference when playing.
